1. “Viva Las Vegas” - Elvis Presley
Back in 1964, Elvis Presley proved that he wasn’t just the King of Rock and Roll, but that he had Vegas on lock as well. Used as a promo single for Presley’s starring role in the film with the same name, “Viva Las Vegas” became a hit for its upbeat tune and catchy chorus. Add on a countless series of cover versions and gold certification from the RIAA, and this classic tune might just be the official theme song of the city that knows how to keep a good secret.
